That is a good point, society as a central point of failure. It's a good way to think about it. We don't have evidence of 10000 year societies in humans. 

We certainly shouldn't try to dictate such things for future generations. But can systems be built which would survive and relay our knowledge to them? How do we send them our bitcoin!! ;)

Can web applications be built to last 10,000 years? 

Humanity hasn't been able to build civilizations that last for 10000 years. Who is to say that the internet will be here in 10000 years? I think that in the long term, we (as a society) are the central point of failure.
